Alpha-pinene-oxide decyclase

In enzymology, an α-pinene-oxide decyclase (EC 5.5.1.10) is an enzyme that catalyzes the chemical reaction

α-pinene oxide ${\displaystyle \rightleftharpoons }$ (Z)-2-methyl-5-isopropylhexa-2,5-dienal

Hence, this enzyme has one substrate, α-pinene oxide, and one product, (Z)-2-methyl-5-isopropylhexa-2,5-dienal.

This enzyme belongs to the family of isomerases, specifically the class of intramolecular lyases. The systematic name of this enzyme class is α-pinene-oxide lyase (decyclizing). This enzyme is also called α-pinene oxide lyase. This enzyme participates in limonene and pinene degradation.
